, Application August 5, 1933, Serial No. eta-I44 3 Claims. (Cl. 28Q33.4)

This invention relates to trailers and particularly'light trailers forcamping or commercial purposes.

An object of the invention is to trailer upon a single roadwheel,employing a simple and novel spring suspension.

Another object is to provide a draw bar mecha-.

nism for a trailer, particularly adapted for connection to a bumper baror bars of a draft vehicle.

A further object is to provide a trailer body with a top, floor, frontand side walls of imperforate character and to give access to said bodyonly through a rear opening thereof, normally closed by doors adapted toexclude dust.

These and various other objects, the invention attains by theconstruction hereinafter described and illustrated in the accompanyingdrawings, wherein: I

Fig. 1 is a view of the trailer in central, longi tudinal, verticalsection.

Fig. 2 is a bottom view of the trailer.

Fig. 3 is a rear view of the trailer showing one of its doors open.

Fig. 4 is a fragmentary cross section taken on the line 4-4 of Fig. 1,showing features of the spring suspension.

Fig. 5 is a sectional detail taken on the line 5-5 of Fig. 2, showingthe connection of a draw bar to the trailer. F

Fig. 6 is a view of the draft arrangement, taken on the line 6--6 ofFig. 1.

Fig. 7 is a sectional detail of said connection 1 taken on the line 1-"!of Fig. 6.

Fig.8 is a fragmentary vertical sectional view of the spring suspension,taken upon the line 8-8 of Fig. 3.

In these views, the reference character I designates a stream-linedbody, formed preferably of sheet-metal, its top, floor, and front andside walls being preferably imperforate. Access to said body is hadthrough the rear end thereof, which is equipped with-a pair of doors 2:These are hinged as indicated at 3 at opposite margins of the dooropening, the hinge axes having a-- slight rearward inclination from topto bottom,

whereby the doors tend to assume and maintain.

Midway between the side walls of the,bqdy, the rear portion of the flooris formed-with an opening 4 accommodating a groundwheel'i; having itscentral plane of rotation substantiallyin the longitudinal central planeof the body. Said t wheel is joumalecl on an axle 6, having its ex mounta light tremities rigidly secured in eyelets 'lrfo the front ends of apair of leaf springs 8. The latter extend lengthwise of the trailer atopposite sides of said wheel, and the rear end of the body is rigidlymounted on the rear ends of said 5 springs, as indicated at 9.

The floor of the trailer is reinforced by a pair of angle bars i0,whichextend substantially the full length of said floor therebeneath,the rear vedvw portions of said bars being marginal to the open- 0 ing4. Said bars are offset at H to extend in relatively close parallelismforwardly of said opening, and between their forward ends is fitted adraw bar l2 which is welded or otherwise rigidly secured to saidbars. Ahousing I2afor. the 15 draft member l6 formedwith a bar I! laterallyprojecting at each side of the draw bar; Upon the'extremities of the barI1 is swiveled a pair 25 of fittings I! each comprising a pair ofcomplementary clamping jaws l8 and i8" for embrac-, ing a rear bumperbar IQ of an automobile or other draft vehicle. 7

' By thus adapting the trailer for attachment so to a rear bumper ratherthan a rear axle, the

risk of subjecting such axle to undue draft strains is avoided.

It will be noted that the vertical and horizontal swivel connectionsestablished by the pin I5 and bar I'l jointly secure the eifect of auniversal joint, permitting any required angular variation in the draftrelation of the pulling vehicle (not shown) and trailer. It is also tobe noted that the described type of draft connection is par- 40ticularly suited to a single wheel type of trailer. The describedtrailer,-because of its use of only one road wheel and the simplicity ofall its structural features may be produced in quantities at relativelylow cost. It is well adapted for hauling 45 light loads of anycharacter, as well as for camping purposes and may be furnished withbeds, if desired. r

- It is to be understood that the form of this invention herewith shownand described is to be taken as a preferred example of the same and thatcertain changes in the shape, size and arrangement of the parts may bemade without departing from the spirit of tins-invention or-the scope ofthe subjoined, claims} 1 What I claim is: M v i 1. A trailer comprisinga body having a floor a'nd side walls and an opening'in the floorsubstantially mid-way between the walls, a pair of leaf springs attachedat corresponding ends to the floor ateach side of said .opening, andextending longitudinally of the vehicle .at a downward divergence to thefloor, and a wheel roly midway between thel'ateral margins of the 'saidwheel at their other floor, a wheel positioned in said opening, a pairof frame members extending beneath the floor lengthwise otthe body, atopposite margins of "said opening, and having forward portions spaced toaccommodate and carry a draw bar between said portions, and means forrotatively mounting said wheel on said frame members.

3. In a trailer as set forth in claim 2, the lastmentioned meanscomprising a pair of springs elongated approximately lengthwise of thevehicle and mounted at corresponding ends upon said frame members, andsupported on and journaling ends.
